I am currently considering one of two Globlink units available from
Aus. PC Market:
- works at 2.4GHz, so could potentially interfere somewhat with the old
802.11b/g network, or
- works at 27Mhz (so may interfere with the R/C car :-), but is $16
cheaper (although it has lower range).
The cheaper Maxtron I/R unit on the Aus PC Market Cordless Keyboards
page is very similar to my existing (not so good) keyboard.
